Abstract
BACKGROUND Psychological stress is associated with changes in salivary flow and composition. However, studies to show the effect of psychological stress on the transcriptome of the salivary gland are limited. This study aims to perform a transcriptomic analysis of the submandibular gland under psychological stress using a chronic restraint stress model of rats. METHODS Sprague-Dawley rats were divided into stress groups and control groups. Psychological stress was induced in the stress group rats by enclosing them in a plastic tube for 4 h daily over 6 weeks. RNA sequencing was performed on RNA extracted from the submandibular gland. The differentially expressed genes were identified, and the genes of interest were further validated using qRT-PCR, immunofluorescence, and western blot. RESULTS A comparison between control and stress groups showed 45 differentially expressed genes. The top five altered genes in RNA sequencing data showed similar gene expression in qRT-PCR validation. The most downregulated gene in the stress group, FosB, was a gene of interest and was further validated for its protein-level expression using immunofluorescence and western blot. The genesets for gene ontology cellular component, molecular function, and KEGG showed that pathways related to ribosome biosynthesis and function were downregulated in the stress group compared to the control. CONCLUSION Psychological stress showed transcriptomic alteration in the submandibular gland. The findings may be important in understanding stress-related oral diseases.

Abstract
This study aims to identify potential variants in the TP63-IRF6 pathway and GREM1 for the etiology of non-syndromic orofacial cleft (NSOFC) among the Vietnamese population. By collecting 527 case-parent trios and 527 control samples, we conducted a stratified analysis based on different NSOFC phenotypes, using allelic, dominant, recessive and over-dominant models for case-control analyses, and family-based association tests for case-parent trios. Haplotype and linkage disequilibrium analyses were also conducted. IRF6 rs2235375 showed a significant association with an increased risk for non-syndromic cleft lip and palate (NSCLP) and cleft lip with or without cleft palate (NSCL/P) in the G allele, with pallele values of 0.0018 and 0.0003, respectively. Due to the recessive model (p = 0.0011) for the NSCL/P group, the reduced frequency of the GG genotype of rs2235375 was associated with a protective effect against NSCL/P. Additionally, offspring who inherited the G allele at rs2235375 had a 1.34-fold increased risk of NSCL/P compared to the C allele holders. IRF6 rs846810 and a G-G haplotype at rs2235375-rs846810 of IRF6 impacted NSCL/P, with p-values of 0.0015 and 0.0003, respectively. In conclusion, our study provided additional evidence for the association of IRF6 rs2235375 with NSCLP and NSCL/P. We also identified IRF6 rs846810 as a novel marker associated with NSCL/P, and haplotypes G-G and C-A at rs2235375-rs846810 of IRF6 associated with NSOFC.

Abstract
Although KCNJ11 mutation is the main cause of neonatal diabetes mellitus, reports of maturity-onset diabetes in the young (MODY) related to KCNJ11 are rare. Here, we report a case of KCNJ11-MODY in a 12-yr-old Japanese female. Hyperglycemia was initially detected during a school urine screening program. Subsequent laboratory examinations revealed impaired insulin secretion; however, no islet autoantibodies were detected. Genetic testing of KCNJ11 revealed a novel heterozygous variant, c.153G>C, p.Glu51Asp. The patient's father had the same mutation and was diagnosed with diabetes at 46 yr of age. KCNJ11-MODY was suspected, and sulfonylurea administration resulted in adequate glycemic control in the patient. The American College of Medical Genetics and Genomics guidelines classify this variant as likely pathogenic, and the effectiveness of sulfonylureas supports its pathogenicity. The patient could be treated with 0.02-0.03 mg/kg/d of glibenclamide, as this mutation may be responsive to only a small amount of sulfonylurea. A detailed family history and sequencing of causative genes, including KCNJ11, may help diagnose diabetes in school-aged patients.

Abstract
Non-alcoholic fatty liver disease (NAFLD) is a general term for fatty liver disease not caused by viruses or alcohol. Fibrotic hepatitis, cirrhosis, and hepatocellular carcinoma can develop. The recent increase in NAFLD incidence worldwide has stimulated drug development efforts. However, there is still no approved treatment. This may be due in part to the fact that non-alcoholic steatohepatitis (NASH) pathogenesis is very complex, and its mechanisms are not well understood. Studies with animals are very important for understanding the pathogenesis. Due to the close association between the establishment of human NASH pathology and metabolic syndrome, several animal models have been reported, especially in the context of overnutrition. In this study, we investigated the induction of NASH-like pathology by enhancing cholesterol absorption through treatment with hydroxypropyl-beta-cyclodextrin (CDX). Female Sprague-Dawley rats were fed a normal diet with normal water (control group); a high-fat (60 kcal%), cholesterol (1.25 %), and cholic acid (0.5 %) diet with normal water (HFCC group); or HFCC diet with 2 % CDX water (HFCC+CDX group) for 16 weeks. Compared to the control group, the HFCC and HFCC+CDX groups showed increased blood levels of total cholesterol, aspartate aminotransferase, and alanine aminotransferase. At autopsy, parameters related to hepatic lipid synthesis, oxidative stress, inflammation, and fibrosis were elevated, suggesting the development of NAFLD/NASH. Elevated levels of endoplasmic reticulum stress-related genes were evident in the HFCC+CDX group. In the novel rat model, excessive cholesterol intake and accelerated absorption contributed to NAFLD/NASH pathogenesis.

Abstract
INTRODUCTION Although breast milk is considered the optimal nutrition for infants, it is also the primary cause of postnatal cytomegalovirus (CMV) infection. Preterm infants with postnatal CMV infections are susceptible to a variety of life-threatening conditions. CASE SUMMARY Twin male infants were delivered via emergency caesarian section at 27 weeks' gestation secondary to maternal complete uterine rupture. The Apgar scores at 1 and 5 min were 1 and 1 for the older twin (Twin A) and 0 and 3 for the younger twin (Twin B). Their birth weights were 1203 g (+ 0.65SD) and 495 g (- 3.79SD) respectively. On day 41, laboratory blood test results for Twin B showed a moderate elevation in C-reactive protein (CRP), thrombocytopenia. CMV quantitative polymerase chain reaction (qPCR) tests in Twin B's urine and blood as well as in the mother's breast milk were positive, but stored, dried umbilical cord CMV qPCR tests were negative. Twin B was diagnosed with a postnatal CMV infection secondary to infected breast milk and ganciclovir was commenced on day 52. Treatment was switched to valganciclovir at 74 days of age, but a negative CMV-DNA level in the blood was not achieved. Postnatal CMV infection in this infant led to an exacerbation of pre-existing bronchopulmonary dysplasia (BPD) and he demised at 182 days of age. CONCLUSION Postnatal cytomegalovirus infections may lead to exacerbations of BPD. Early use of raw breast milk in preterm infants should be done with careful consideration of this potential complication.

Abstract
In patients with diabetic kidney disease (DKD), the estimated glomerular filtration rate (eGFR) or creatinine clearance rate (Ccr) is always used as an index of decline in renal function. However, there are few animal models of DKD that could be used to evaluate renal function based on GFR or Ccr. For this reason, it is desirable to develop animal models to assess renal function, which could also be used for the evaluation of novel therapeutic agents for DKD. Therefore, we aimed to develop such animal model of DKD by using spontaneously hypertensive rat (SHR)/NDmcr-cp (cp/cp) rats with the characteristics of obese type 2 diabetes and metabolic syndrome. As a result, we have found that unilateral nephrectomy (UNx) caused a chronic Ccr decline, development of glomerular sclerosis, tubular lesions, and tubulointerstitial fibrosis, accompanied by renal anemia. Moreover, losartan-mixed diet suppressed the Ccr decline in UNx-performed SHR/NDmcr-cp rats (UNx-SHR/cp rats), with improvement in renal anemia and histopathological changes. These results suggest that UNx-SHR/cp rats could be used as a DKD model for evaluating the efficacy of therapeutic agents based on suppression of renal function decline.

Abstract
BACKGROUND/AIM Cyclooxygenase is an enzyme that transforms arachidonic acid to prostaglandins. Cyclooxygenase-2 (COX-2) is an isoform of cyclooxygenase. There exist many reports on the expression levels of COX-2 in cancer tissues, and prognosis of cancer patients has been reported to be related to COX-2 up-regulation. In the present study we assessed the suppressive effect of AHCC® on the expression of COX-2 in QRsP-11cells. MATERIALS AND METHODS QR-32 is a clone which was derived from murine fibrosarcoma BMT-11 cells by treatment with quercetin. These clone cells regress spontaneously after injection into C57BL/6 mice. QRsP-11 is a clone derived from QR-32, showing very aggressive tumorigenicity. AHCC® is a standardized extract of cultured Lentinula edodes mycelia and has been reported to exert suppressive effects on various tumor-associated proteins including HSP27. The protein levels of COX-2 in QR-32 and QRsP-11 cells were compared by using western blotting. Furthermore, the expression levels of COX-2 were assessed in QRsP-11 cells after AHCC®-treatment. RESULTS Western blot analysis showed a significant up-regulation of COX-2 in QRsP-11 cells compared to QR-32 cells. In vitro AHCC®-treatment increased COX-2 expression levels in QRsP-11 cells contrary to expectations. CONCLUSION When using AHCC® in cancer treatment, it might be important to decrease COX-2 expression by means of non-steroidal anti-inflammatory drugs (NSAIDs), such as aspirin. Further studies are required to clarify the mechanism of up-regulation of COX-2 through AHCC®-treatment.

Although prostate cancer cells grow slowly in the local original site, once the cancer cells spread to distant organs they grow rapidly and show very aggressive features. Cortactin is a protein that regulates the actin cytoskeleton and plays crucial roles in cancer metastasis. Up-regulated cortactin is correlated with the metastatic capacity of prostate cancer cells. AHCC®, a standardized extract of cultured Lentinula edodes mycelia, has been previously reported to have cortactin-down-regulating effects on human pancreatic cancer cells. In the present study, the effects of AHCC® treatment on cortactin levels in prostate cancer cells was evaluated. MATERIALS AND METHODS LNCaP.FGC, DU145, and PC-3 are human prostate cancer cell lines. LNCaP.FGC is well differentiated, androgen-dependent, and poorly metastatic. DU145 is less differentiated, androgen-independent, and moderate metastatic. PC-3 is less differentiated, androgen-independent, and highly metastatic. The effects of AHCC® treatment on cortactin levels in prostate cancer cells was evaluated by western blot. RESULTS In vitro AHCC® treatment decreased cortactin levels in LNCaP.FGC and DU145 cells but did not change those in PC-3 cells. CONCLUSION AHCC® treatment down-regulated cortactin expression in poor and moderate metastatic LNCaP.FGC and DU145 cells but showed no effect on cortactin expression in the highly metastatic PC-3 cells. Further studies are required to elucidate the mechanism of the resistance to AHCC® treatment in highly metastatic PC-3 cells.

Abstract
The oxytocin receptor (OXTR) knockout mouse is a model of autism spectrum disorder, characterized by abnormalities in social and olfactory behaviors and learning. Previously, we demonstrated that OXTR plays a crucial role in regulating aversive olfactory behavior to butyric acid odor. In this study, we attempted to determine whether coffee aroma affects the abnormal olfactory behavior of OXTR-Venus knock-in heterozygous mice [heterozygous OXTR (±) mice] using a set of behavioral and molecular experiments. Four-week repeated exposures of heterozygous OXTR (±) mice to coffee odor, containing three kairomone alkylpyrazines, rescued the abnormal olfactory behaviors compared with non-exposed wild-type or heterozygous OXTR (±) mice. Increased Oxtr mRNA expression in the olfactory bulb and amygdala coincided with the rescue of abnormal olfactory behaviors. In addition, despite containing the kairomone compounds, both the wild-type and heterozygous OXTR (±) mice exhibited a preference for the coffee odor and exhibited no stress-like increase in the corticotropin-releasing hormone, instead of a kairomone-associated avoidance response. The repeated exposures to the coffee odor did not change oxytocin and estrogen synthetase/receptors as a regulator of the gonadotropic hormone. These data suggest that the rescue of abnormal olfactory behaviors in heterozygous OXTR (±) mice is due to the coffee odor exposure-induced OXTR expression.

Abstract
Ewing's sarcoma is the second most common bone malignancy in children or young adults and is caused by an oncogenic transcription factor by a chromosomal translocation between the EWSR1 gene and the ETS transcription factor family. However, the transcriptional mechanism of EWS-ETS fusion proteins is still unclear. To identify the transcriptional complexes of EWS-ETS fusion transcription factors, we applied a proximal labeling system called BioID in Ewing's sarcoma cells. We identified AHDC1 as a proximal protein of EWS-ETS fusion proteins. AHDC1 knockdown showed a reduced cell growth and transcriptional activity of EWS-FLI1. AHDC1 knockdown also reduced BRD4 and BRG1 protein levels, both known as interacting proteins of EWS-FLI1. Our results suggest that AHDC1 supports cell growth through EWS-FLI1.

Abstract
Transient receptor potential vanilloid 1 (TRPV1) is mainly expressed in nociceptive primary sensory neurons and acts as a sensor for heat and capsaicin. The functional properties of TRPV1 have been reported to vary among species and, in some cases, the species difference in its thermal sensitivity is likely to be associated with thermal habitat conditions. To clarify the functional properties and physiological roles of TRPV1 in aquatic vertebrates, we examined the temperature and chemical sensitivities of TRPV1 in masu salmon (Oncorhynchus masou ishikawae, Om) belonging to a family of salmonids that generally prefer cool environments. First, behavioral experiments were conducted using a video tracking system. Application of capsaicin, a TRPV1 agonist, induced locomotor activities in juvenile Om. Increasing the ambient temperature also elicited locomotor activity potentiated by capsaicin. RT-PCR revealed TRPV1 expression in gills as well as spinal cord. Next, electrophysiological analyses of OmTRPV1 were performed using a two-electrode voltage-clamp technique with a Xenopus oocyte expression system. Heat stimulation evoked an inward current in heterologously expressed OmTRPV1. In addition, capsaicin produced current responses in OmTRPV1-expressing oocytes, but higher concentrations were needed for its activation compared to the mammalian orthologues. These results indicate that Om senses environmental stimuli (heat and capsaicin) through the activation of TRPV1, and this channel may play important roles in avoiding environments disadvantageous for survival in aquatic vertebrates. Capsaicin evoked behavioral responses of Oncorhynchus masou ishikawae (Om). The behavioral response to heat was potentiated by capsaicin. Heterologously expressed OmTRPV1 was activated by heat and capsaicin.

Abstract
BACKGROUND/AIM Fucoxanthinol (FxOH), a marine carotenoid, induces apoptosis and anoikis in human colorectal cancer (CRC) DLD-1 cells via the down-regulation of chloride intracellular channel 4 (CLIC4) expression, a key molecule for apoptosis. However, whether FxOH is susceptible to CLIC4 expression and its regulatory mechanisms in human CRC cells remains unknown. We investigated the inhibitory effects of FxOH on six types of human CRC cells with CLIC4 regulation. MATERIALS AND METHODS The association between FxOH and CLIC4 was investigated using gene knockdown, overexpression, and transcriptome analyses. RESULTS CLIC4 expression in CRC cells was a significant factor associated with sensitivity to FxOH. CLIC4 regulates many cancer-related signals and participates in growth inhibition in FxOH-treated DLD-1 cells. Both CLIC4 knockdown and overexpression attenuated the inhibitory effects of FxOH on DLD-1 cells. CONCLUSION Our findings suggest that the protein expression of CLIC4 and its regulating mechanisms play significant roles regarding cell death in human CRC cells by FxOH treatment. Further investigation by in vitro and in vivo models is needed to determine the effect of CLIC4.

Abstract
Fucoxanthin (Fx) is a critical pigment required for photosynthesis in brown algae and microalgae. Fx is also a dietary marine carotenoid that with potent anticancer activity in vitro and in vivo. Some popular light meals for increased satiety, such as biscuits, cereals, and crackers, are frequently fortified with micronutrients for human health benefits. However, data on the anticancer potential of Fx-supplemented light meals in humans and animal models remain limited. In the present study, we investigated the anticancer effects of a Fx-supplemented biscuit using a carcinogenic murine azoxymethane/dextran sodium sulfate (AOM/DSS) model. We observed that periodic administration of biscuits containing 0.3% Fx (Fx-biscuit) at an interval of 3 days (each 15 h) per week for 15 weeks significantly inhibited colorectal carcinogenesis in AOM/DSS mice. Comprehensive gene analysis demonstrated that the Fx-biscuit significantly altered the expression of 138 genes in the colorectal mucosal tissue of the mice. In particular, the expression of heat shock protein 70 (HSP70) genes, Hspa1b (-35.7-fold) and Hspa1a (-34.9-fold), was markedly downregulated. HSP70 is a polyfunctional chaperone protein that is involved in cancer development. Compared to the control-biscuit group, the number of cells with markedly high fluorescence for HSP70 protein (HSP70high) in colorectal mucosal crypts and adenocarcinomas significantly reduced by 0.3- and 0.2-fold, respectively, in the Fx-biscuit group. Our results suggested that Fx-biscuit possesses chemopreventive potential in the colorectal cancer of AOM/DSS mice via the downregulation of HSP70.

Abstract
Diabetic nephropathy, included in diabetic kidney disease (DKD), is the primary disease leading to end-stage renal disease (ESRD) or dialysis treatment, accounting for more than 40% of all patients with ESRD or receiving dialysis. Developing new therapeutics to prevent the transition to ESRD or dialysis treatment requires an understanding of the pathophysiology of DKD and an appropriate animal model for drug efficacy studies. In this study, we investigated the pathophysiology of diabetic kidney disease with type 2 diabetes in uninephrectomized db/db mice. In addition, the nephrectomized db/db mice from 10 weeks to 42 weeks were used to assess the efficacy of long-term administration of the angiotensin-II–receptor antagonist losartan. The blood and urinary biochemical parameters and the blood pressure which is a main pharmacological endpoint of the losartan therapy, were periodically measured. And at the end, histopathological analysis was performed. Uninephrectomized db/db mice clearly developed obesity and hyperglycemia from young age. Furthermore, they showed renal pathophysiological changes, such as increased urinary albumin-creatinine ratio (UACR) (the peak value 3104±986 in 40-week-old mice), glomerular hypertrophy and increased fibrotic areas in the tubulointerstitial tubules. The blood pressure in the losartan group was significantly low compared to the normotensive Vehicle group. However, as expected, Losartan suppressed the increase in UACR (829±500) indicating the medication was sufficient, but the histopathological abnormalities including tubular interstitial fibrosis did not improve. These results suggest that the uninephrectomized db/db mice are useful as an animal model of the severe DKD indicated by the comparison of the efficacy of losartan in this model with the efficacy of losartan in clinical practice.

Abstract
Transient receptor potential vanilloid 1 (TRPV1) is known as a receptor of capsaicin, a spicy ingredient of chili peppers. It is also sensitive to a variety of pungent compounds and is involved in nociception. Here, we focused on the structural characteristics of capsaicin, and investigated whether vanillylmanderic acid (VMA), vanillic acid (VAcid), vanillyl alcohol (VAlc), vanillyl butyl ether (VBE), and vanillin, containing a vanillyl skeleton similar to capsaicin, affected the TRPV1 activities. For detection of TRPV1 activity, intracellular Ca2+ concentration ([Ca2+]i) was measured in HEK 293 cells heterologously expressing mouse TRPV1 (mTRPV1-HEK) and in mouse sensory neurons. Except for vanillin, four vanilloid analogues dose-dependently increased [Ca2+]i in mTRPV1-HEK. The solutions that dissolved VMA, VAcid and vanillin at high concentrations were acidic, whereas those of VAlc and VBE were neutral. Neutralized VAcid evoked [Ca2+]i increases but neutralized VMA did not. Mutation of capsaicin-sensing sites diminished [Ca2+]i responses to VAcid, VAlc and VBE. VAcid, VMA, and vanillin suppressed the activation of TRPV1 induced by capsaicin. VAcid and VMA also inhibited the acid-induced TRPV1 activation. In sensory neurons, VMA diminished TRPV1 activation by capsaicin or acids. The present data indicate that these structural characteristics of chemical compounds on TRPV1 may provide strategies for the development of novel analgesic drugs targeting nociceptive TRPV1.

Abstract
Fucoxanthin (Fx) is a marine carotenoid with anti-inflammatory and anti-cancer properties in various animal models of carcinogenesis. However, there is currently no information on the effects of Fx in animal models of pancreatic cancer. We investigated the chemopreventive effects of Fx in C57BL/6J mice that received allogenic and orthotopic transplantations of cancer cells (KMPC44) derived from a pancreatic cancer murine model (Ptf1aCre/+; LSL-krasG12D/+). Using microarray, immunofluorescence, western blot, and siRNA analyses, alterations in cancer-related genes and protein expression were evaluated in pancreatic tumors of Fx-administered mice. Fx administration prevented the adenocarcinoma (ADC) development of pancreatic and parietal peritoneum tissues in a pancreatic cancer murine model, but not the incidence of ADC. Gene and protein expressions showed that the suppression of chemokine (C-C motif) ligand 21 (CCL21)/chemokine receptor 7 (CCR7) axis, its downstream of Rho A, B- and T-lymphocyte attenuator (BTLA), N-cadherin, αSMA, pFAK(Tyr397), and pPaxillin(Tyr31) were significantly suppressed in the pancreatic tumors of mice treated with Fx. In addition, Ccr7 knockdown significantly attenuated the growth of KMPC44 cells. These results suggest that Fx is a promising candidate for pancreatic cancer chemoprevention that mediates the suppression of the CCL21/CCR7 axis, BTLA, tumor microenvironment, epithelial mesenchymal transition, and adhesion.

Abstract
Ranunculus (Ranunculus asiaticus L.) is one of the most popular cut flowers in Japan. However, the infection rate of ranunculus mild mosaic virus (RanMMV) in ranunculus plants has been gradually increasing during cultivation, suggesting that RanMMV may be transmitted from weeds to ranunculus plants in cultivation fields. In our survey, RanMMV in R. japonicus, R. tachiroei, R. cantoniensis, Geranium carolinianum, Vicia sativa, V. tetrasperma and V. hirsute in ranunculus fields and noncultivation regions in Japan was detected. Ranunculaceae weeds grow all year in cultivation fields, unlike R. asiaticus, indicating that these weeds may be a source of RanMMV infection. In addition, a pairwise comparison of CP genes between RanMMV isolates taken from R. asiaticus, R. japonicus, and R. tachiroei showed high nucleotide (98·1-100%) and amino acid (98·5-100%) identities. These results support the hypothesis that RanMMV may be transmitted between Ranunculaceae weeds and R. asiaticus plants. Thus, virus control should focus on removing host weeds from the cultivation fields.

Abstract
Fucoxanthin (Fx) has shown potential cancer chemopreventive functions in a carcinogenic murine azoxymethane/dextran sodium sulfate (AOM/DSS) model. However, the molecular mechanisms based on transcriptome profiles in vivo remain poorly understood. We investigated Fx-dependent alterations of the transcriptome with cancer-associated proteins in colorectal mucosal tissue obtained from AOM/DSS mice with or without Fx treatment. Fx administration (50 mg/kg body weight for 14 weeks) significantly prevented the onset of colorectal adenocarcinoma in AOM/DSS mice. A transcriptome analysis revealed that 11 signals, including adhesion, cell cycle, chemokine receptor, interleukin, MAPK, PI3K/AKT, p53, RAS, STAT, TGF-β, and Wnt were remarkably altered by Fx administration. In particular, chemokine (C-C motif) receptor 1 (Ccr1), which is contained in a gene set related to cytokine-cytokine receptor interactions, was the only significantly down-regulated gene after Fx administration for both 7 and 14 weeks. CCR1, AKT, Cyclin D1, and Smad2 were found to play central roles in the 11 signals shown above. Fx administration significantly down-regulated CCR1 (0.3- and 0.5-fold in mucosal crypts and lamina propria, respectively), pAKT(Ser473) (0.2-fold in mucosal crypts), Cyclin D1 (0.4-fold in mucosal crypts), and pSmad2(Ser465/467) (0.7-fold in mucosal crypts) compared with proteins in these tissues of control mice after Fx administration for 14 weeks. Our findings suggested that Fx exerts a chemopreventive effect in AOM/DSS mice through attenuation of CCR1 expression along with 11 cancer-associated signals.

Abstract
BACKGROUND/AIM Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) has been affecting Hokkaido, Japan since late February 2020 until present. The aim of this study was to report the relationship between anti-SARS-CoV-2 antibody-positive and SARS-CoV-2 PCR-positive cases by analyzing anti-SARS-CoV-2 antibodies (IgG and total-Ig). PATIENTS AND METHODS Serum samples were collected from care workers and nurses in two nursing homes and two hospitals which underwent virus outbreak. All people were confirmed to be SARS-CoV-2-positive by RT-qPCR and their sera was analyzed for anti-SARS-CoV-2 antibodies (IgG and total-Ig). RESULTS Although 34 out of 43 samples (79.1%) showed enough amount of anti-SARS-CoV-2 antibodies, 9 RT-qPCR -positive samples (20.9%) showed absence of anti-SARS-CoV-2 antibodies in their sera. CONCLUSION The results that 20.9% of RT-qPCR-positive samples with SARS-CoV-2 showed absence of anti-SARS-CoV-2 antibodies provides a possibility that the innate immune reaction could eliminate the virus without activating adaptive immune reaction.

Abstract
Polysulfide (PS), an endogenous sulfur compound, generated by oxidation of hydrogen sulfide, has a stimulatory action on the nociceptive TRPA1 channel. TRPA1 is also activated by reactive oxygen species such as hydrogen peroxide (H2O2) produced during inflammation. Here, we examined the effect of PS on H2O2-induced responses in native and heterologously expressed TRPA1 using a cell-based calcium assay. We also carried out behavioral experiments in vivo. In mouse sensory neurons, H2O2 elicited early TRPA1-dependent and late TRPA1-independent increases of [Ca2+]i. The former was suppressed by the pretreatment with PS. In cells heterologously expressed TRPA1, PS suppressed [Ca2+]i responses to H2O2. Simultaneous measurement of [Ca2+]i and the intracellular PS level revealed that scavenging effect of PS was not related to the inhibitory effect. Removal of extracellular Ca2+, a calmodulin inhibitor and dithiothreitol attenuated the inhibitory effect of PS. Pretreatment with PS diminished nociceptive behaviors induced by H2O2. The present data suggest that PS suppresses oxidative stress-induced TRPA1 activation due to cysteine modification and Ca2+/calmodulin signaling. Thus, endogenous sulfurs may have regulatory roles in nociception via functional changes in TRPA1 under inflammatory conditions.

Abstract
BACKGROUND/AIM Fucoxanthinol (FxOH), a predominant metabolite from fucoxanthin (Fx), can exert potential anti-cancer effects in various cancers. However, limited data are available on the effect of FxOH or Fx on pancreatic cancer. The present study investigated the effect of FxOH on a cell line derived from pancreatic cancer tissue developed in Ptf1aCre/+; LSL-k-rasG12D/+ mice. MATERIALS AND METHODS Using flow-cytometric, microarrays, and western blotting analyses, alterations in FxOH-induced apoptosis-related gene expression and protein levels were evaluated in a mice pancreatic cancer cell line, KMPC44. RESULTS FxOH significantly arrested the cells at S phase along with suppression of many gene sets, such as cytokine- cytokine receptor interaction and cell adhesion molecule CAMS. Moreover, attenuated protein levels for cytokine receptors, adhesion, phosphatidylinositol-3 kinase/protein kinase B, and mitogen-activated protein kinase were observed. CONCLUSION FxOH may prevent pancreatic cancer development in a murine cancer model.

Abstract
Fucoxanthin and its metabolite fucoxanthinol (FxOH), highly polar xanthophylls, exert strong anticancer effects against many cancer cell types. However, the effects of Fx and FxOH on pancreatic cancer, a high mortality cancer, remain unclear. We herein investigated whether FxOH induces apoptosis in human pancreatic cancer cells. FxOH (5.0 μmol/L) significantly promoted the growth of human pancreatic cancer PANC-1 cells, but induced apoptosis in human colorectal cancer DLD-1 cells. A microarray-based gene analysis revealed that the gene sets of cell cycle, adhesion, PI3K/AKT, MAPK, NRF2, adipogenesis, TGF-β, STAT, and Wnt signals in PANC-1 cells were markedly altered by FxOH. A western blot analysis showed that FxOH up-regulated the expression of integrin β1 and PPARγ as well as the activation of pFAK(Tyr397), pPaxillin(Tyr31), and pAKT(Ser473) in PANC-1 cells, but exerted the opposite effects in DLD-1 cells. Moreover, the expression of FYN, a downstream target of integrin subunits, was up-regulated (7.4-fold by qPCR) in FxOH-treated PANC-1 cells. These results suggest that FxOH accelerates the growth of PANC-1 cells by up-regulating the expression of integrin β1, FAK, Paxillin, FYN, AKT, and PPARγ.

Abstract
Glomerular hyperfiltration is observed in an early stage of kidney diseases including diabetic nephropathy. A better understanding of pathophysiological changes in glomerular hyperfiltration is essential for development of new therapies to prevent kidney disease progression. In this study, we investigated glomerular changes including glomerular filtration rate (GFR) and glomerular size in the Spontaneously Diabetic Torii (SDT) fatty rat, an obese type 2 diabetic model, and we also evaluated pharmacological effects of the sodium glucose cotransporter 2 inhibitor dapagliflozin on the renal lesions. Dapagliflozin was administered to SDT fatty rats from 5 to 17 weeks of age. Blood and urinary biochemical parameters were periodically measured. GFR was determined by transdermal GFR monitor at 16 weeks of age and histopathological analysis was performed at 17 weeks of age. SDT fatty rat developed severe hyperglycemia and exhibited pathophysiological abnormalities in the kidney, such as an increased GFR, glomerular hypertrophy and tissue lesions. Dapagliflozin achieved good glycemic control during the experimental period, inhibited the increase in GFR, and improved histopathological abnormalities in tubules. These results suggest that the SDT fatty rat is a useful model for analyzing the pathogenesis of diabetic nephropathy during its early stage and dapagliflozin improves not only hyperglycemia but also glomerular hyperfiltration and tubule lesions in SDT fatty rat.

Abstract
We report on the frozen-spin polarized hydrogen-deuteride (HD) targets for photoproduction experiments at SPring-8/LEPS. Pure HD gas with a small amount of ortho-H2 (∼0.1%) and a very small amount of para-D2 (∼0.001%) was liquefied and solidified by liquid helium. The temperature of the produced solid HD was reduced to about 30 mK with a dilution refrigerator. A magnetic field (17 T) was applied to the HD to grow the polarization with the static method. After the aging of the HD at low temperatures in the presence of a high-magnetic field strength for three months, the polarization froze. Almost all ortho-H2 molecules were converted to para-H2 molecules. Most remaining para-D2 molecules were converted to ortho-D2 molecules. The para-H2 and ortho-D2 molecules exhibited weak spin interactions with the HD. If the concentrations of the ortho-H2 and para-D2 were reduced appropriately at the beginning of the aging process, the aging time can be shortened. We have developed a new nuclear magnetic resonance (NMR) system to measure the relaxation times (T1) of the 1H and 2H nuclei with two frequency sweeps at the respective frequencies of 726 MHz and 111 MHz and succeeded in the monitoring of the polarization build-up at decreasing temperatures from 600 mK to 30 mK at 17 T. Automatic NMR measurements with the frequency sweeps enabled us to omit the use of a manual tuning circuit and to remove magnetic field sweeps with eddy current heat. This technique enables us to optimize the concentration of the ortho-H2 and to efficiently polarize the HD target within a shortened aging time.

Abstract
OBJECTIVES Behçet's disease (BD) is characterised by repeated acute inflammatory attacks with aphthous ulcers of the oral mucosa, uveitis of the eyes, skin symptoms, and genital ulcers. Although its aetiology is still unknown, there is evidence of the involvement of oral bacteria in systemic diseases. Various types of oral bacteria may be involved in the development and progression of BD. The present study investigated alterations in the oral flora of patients with BD in Mongolia. We collected saliva samples from the Mongolian BD group and healthy control (HC) group, and the oral flora were analysed using next-generation sequencer (NGS). METHODS DNA was extracted from the unstimulated saliva samples from the 47 BD and 48 HC subjects. The DNA was amplified from the V3-V4 region of 16S rRNA using PCR, and the data were acquired using NGS. Based on the obtained data, we analysed the alpha diversity, beta diversity, and bacterial taxonomy of the salivary flora. RESULTS Beta diversity differed significantly between the BD and HC flora, but no significant differences were observed in alpha diversity. We found that the proportions of three genera - an S24-7 family unknown species, a mitochondria family unknown species, and Akkermansia species associated with IL-10 production - were significantly lower in the BD than in the HC group. CONCLUSIONS The reduced proportions of the S24-7 family and symbiotic Akkermansia species may be key phenomena in the oral flora of patients with BD.

Abstract
Transient receptor potential vanilloid 1 (TRPV1), a non-selective cation channel, is mainly expressed in nociceptive primary sensory neurons. Sensitivity of TRPV1 to several stimuli is known to vary among species, specifically, the avian orthologue is nearly insensitive to capsaicin. Extracellular sodium ions ([Na+]o) regulate TRPV1 activity in mammals, but their regulatory role on chicken TRPV1 (cTRPV1) is unknown. Here, we focused on the actions of capsaicin and low [Na+]o on cTRPV1 activity. In chicken dorsal root ganglion (cDRG) neurons, capsaicin elicited [Ca2+]i increases, but its effective concentration was much higher than those in mammals. Low [Na+]o evoked [Ca2+]i increases in cDRG neurons in a decreasing [Na+]o-dependent manner and the complete removal of [Na+]o (0Na) produced maximal effects. The population of 0Na-sensitive neurons was mostly overlapped with those of proton- and capsaicin-sensitive ones. Low [Na+]o synergistically potentiated the capsaicin- and proton-induced TRPV1 activation in cDRG neurons. In HEK293 cells expressing cTRPV1 (cTRPV1-HEK), capsaicin elicited [Ca2+]i increases with an EC50 of 11.8 µM, and low [Na+]o also did. Well-defined mammalian TRPV1 antagonists hardly suppressed cTRPV1 activation by low [Na+]o. 0Na evoked outwardly rectified currents in cTRPV1-HEK. Mutagenesis analyses revealed a possible interaction of [Na+]o with the proton-binding sites of cTRPV1. The administration of capsaicin and 0Na to chick eyes elicited pain-related behaviors. These results suggest that low [Na+]o is capable of activating cTRPV1 in vitro, resulting in pain in vivo. Our data demonstrate that characterization of the cTRPV1 function is important to understand activation mechanisms of TRPV1.

Abstract
Fucoxanthin is a marine xanthophyll found in edible brown algae, and a metabolite, fucoxanthinol (FxOH), possesses a potent apoptosis inducing effect in many cancer cells. Chloride intracellular channel 4 (CLIC4) is a member of the CLIC family that plays an important role in cancer development and apoptosis. However, the role of CLIC4 in FxOH-induced apoptosis is not well understood. In this study, we investigated whether CLIC4 affects the apoptotic properties of FxOH in human colorectal cancer (CRC) cells under FxOH treatment. Treating human CRC DLD-1 cells with 5.0 μmol/L FxOH significantly induced apoptosis. FxOH downregulated CLIC4, integrin β1, NHERF2 and pSmad2 (Ser465/467) by 0.6-, 0.7-, 0.7-, and 0.5-fold, respectively, compared with control cells without alteration of Rab35 expression. No colocalizing change was observed in CLIC4-related proteins in either control or FxOH-treated cells. CLIC4 knockdown suppressed cell growth and apoptosis. Interestingly, apoptosis induction by FxOH almost disappeared with CLIC4 knockdown. Our findings suggested that CLIC4 could be involved in FxOH-induced apoptosis in human CRC.

Abstract
We measured missing mass spectrum of the ^{12}C(γ,p) reaction for the first time in coincidence with potential decay products from η^{'} bound nuclei. We tagged an (η+p) pair associated with the η^{'}N→ηN process in a nucleus. After applying kinematical selections to reduce backgrounds, no signal events were observed in the bound-state region. An upper limit of the signal cross section in the opening angle cosθ_{lab}^{ηp}<-0.9 was obtained to be 2.2 nb/sr at the 90% confidence level. It is compared with theoretical cross sections, whose normalization ambiguity is suppressed by measuring a quasifree η^{'} production rate. Our results indicate a small branching fraction of the η^{'}N→ηN process and/or a shallow η^{'}-nucleus potential.

Background
Takotsubo syndrome is generally considered a benign disease with a reversible condition; however, hemodynamic and electrical instability during the acute phase exposes patients to the risk of serious adverse in-hospital events. The purpose of this study was to investigate the prognostic value of the left ventricular longitudinal and circumferential function in patients with TTS during the acute phase.
Methods
We divided the 27 patients with TTS (77.4 ± 10.2 years old, 21 females) into two groups; the severe group (SG) of 9 patients (in-hospital death, mechanical assist devices such as IABP or ECMO, oozing rupture) and non-severe group (NSG) of 18 patients. The echocardiographic examination on admission, catheter hemodynamic assessment, and laboratory data, and ST-T change in electrocardiogram were compared between two groups.
Results
There were no differences in age, laboratory data, electrocardiogram findings between the two groups. The LVEF was lower in SG (35.3 ± 6.1% vs. 45.9 ± 13.5%, p = 0.03). The index of Ballooning, the ratio of the systolic left ventricular diameter of ballooning segments to that of basal segments, was higher in SG (2.07 ± 0.61% vs.1.60 ± 0.32%, p = 0.016). The circumferential fractional shortening (CFS) of ballooning segments was lower in SG (4.6 ± 3.2% vs. 18.2 ± 8.2%, p = 0.00007), CFS of basal segments was not different between the two groups, and the ratio of CFS of ballooning segments to CFS of basal segments (CFS imbalance index) was lower in SG (5.60 ± 3.84 vs. 10.83 ± 3.92, p = 0.00003). The left ventricular longitudinal fractional shortening was lower in SG (0.12 ± 0.09 vs. 0.46 ± 0.19, p = 0.00003). The absolute value of GLS was lower in SG (7.6 ± 4.3% vs. 13.0 ± 3.6%, p = 0.002). In all three cases of in-hospital death, the CFS imbalance index was lower than 0.14.
Conclusion
In patients with TTS, left ventricular longitudinal and circumferential function could be related to serious adverse in-hospital events.

Abstract
Prader-Willi syndrome (PWS) is a well-known imprinting disorder arising from a loss of paternally imprinted gene(s) at 15q11.2-q13. We report a typical PWS patient with a balanced reciprocal translocation, 46, XY, t(15;19)(q11.2;q13.3). After Illumina whole-genome sequencing, we used BreakDancer-1.45 software to predict candidate breakpoints and manually investigated via the Integrated Genome Viewer. Breakpoint PCR followed by Sanger sequencing determined the t(15;19) breakpoints. We investigated the expression of upstream/centromeric and downstream/telomeric genes of the 15q11.2 breakpoint by reverse transcriptase PCR, using total RNA extracted from the patient's lymphoblasts. Of note, the expression of paternally expressed genes PWAR6, SNORD109A/B, SNORD116, IPW, and PWAR1, downstream of the breakpoint, was abolished. Interestingly, the breakpoint did not destroy protein coding genes or individual snoRNAs. These results indicate that these genes may play a major role in the PWS phenotype.

Abstract
Abstract
Background: It is well known that the prognosis of non pCR TNBC patients was poor after anthracycline and taxan treatment. For such patients, capecitabine seems to be effective to reduce recurrence based on the HR 0.58 of the CREATE X trial (Masuda, N. et al. Adjuvant Capecitabine for Breast Cancer after Preoperative Chemotherapy. N Engl J Med. 376, 2147. 2017) . However, the target of capecitabine is still unclear for TNBC. We classified non pCR tumors as BRCAness and Sporadic using BRCAness test(MRC-Holland, Amsterdam, the Netherlands). The recurrence rate of the BRCAness group was about 70%. Carboplatine is expected to be effective against BRCAness tumors, as it is a DNA damaging agent. In this study BRCAness can be checked just before carboplatin treatment using surgical specimens. Then the efficacy of carboplatin will be directly known to make comparison between DFS in the carboplatin group and that of the observation group.
Trial design: This is anopen label, randomized phase III study that will enroll TNBC with residual invasive cancer after surgery with preoperative chemotherapy including both anthracycrine and taxan. Patients are randomly assigned to either the carboplatin group or observation group. The patients in the carboplatin group are treated with carboplatin at AUC 6 and those in the observation group are observed at only 3 years.
Eligibility criteria:
1) ER and PgR<1%, HER2 0, 1+ or 2+ with FISH negative on core needle biopsy before the chemotherapy and surgical specimens.
2) Preoperative chemotherapy including both anthracycrine and taxan.
3) Residual invasive cancer on breast tumors or lymph node metastasis in surgical specimens.
4) 20-79 year old women.
5) No chemotherapy within 5 years.
6) Not bilateral breast cancer, without metastasis, no prior breast cancer.
7) No severe bone marrow suppression.
Specific aims:Primary objective is DFS (Disease Free Survival). Secondary objectives are overall survival and safety.
STATISTICAL METHODS:
The 3 years recurrence rate of the observation group was estimated as 40% and hazard ratio at 0.58 based on the CREATE X trial. For both groups, 135 patients are necessary. This study is powered to approximately 80% to test the superiority of carboplatin group at a 2-sided α=0.05 using a stratified log-rank test.
Activation Date:22ndMarch 2018. No patients had been enrolled till 3rd July.

Abstract
BACKGROUND/AIM We have previously reported that treatment of pancreatic cancer cells with active hexose-correlated compound (AHCC), an extract of a basidiomycete mushroom, decreases the levels of tumor-associated proteins including heat-shock protein 27 (HSP27), heat shock factor 1 (HSF1) and sex-determining region Y-box 2 (SOX2). The transmembrane glycoprotein, CUB domain-containing protein 1 (CDCP1) has been reported to be up-regulated in various cancers, and be associated with invasion and metastasis. The aim of this study was to examine the effect of AHCC on the expression of CDCP1 in KLM1-R cells. MATERIALS AND METHODS Gemcitabine-resistant pancreatic cancer cells (KLM1-R) were treated with AHCC (10 mg/ml) for 48 h. Western blot analysis of cell extracts with anti-CDCP1 or anti-actin antibodies was performed to assess the expression of CDCP1. RESULTS Expression of CDCP1 was reduced by AHCC treatment of KLM1-R cells, whereas expression of actin was not affected. The ratio of intensities of CDCP1/actin in AHCC-treated KLM1-R cells was significantly suppressed (p<0.05) compared to untreated cells. CONCLUSION AHCC down-regulated CDCP1 expression and inhibited the malignant progression of pancreatic cancer cells.

Abstract
Oxytocin (OXT) and its receptor (OXTR) regulate reproductive physiology (i.e. parturition and lactation), sociosexual behavior, learned patterns of behavior and olfactory behavior in social contexts. To characterize the function of OXTR in basic olfactory behavior, the present study compared the behavioral responses of homozygous, heterozygous and wild-type mice when these mice were confronted with an unpleasant odorant (butyric acid) in a custom-made Y-maze in the absence of a social context. Wild-type mice avoided the first encounter with the butyric acid odorant, whereas homozygous and heterozygous mice did not. However, both heterozygous and wild-type mice habituated when confronted with the butyric odorant again on the following 2 days. By contrast, homozygous mice failed to habituate and instead avoided the location of the odorant for at least 3 days. These data suggest that homozygous and heterozygous mice display abnormal olfactory responses to the presentation of an unpleasant odorant. Our studies demonstrate that OXTR plays a critical role in regulating olfactory behavior in the absence of a social context. Summary: Homozygous mice exhibited abnormal olfactory behaviors, namely failure in the acute avoidance of butyric acid and in habituation behavior, in the absence of a social context.

Abstract
A single nucleotide polymorphism in the ABCC11 gene, 538G>A (rs17822931), is known to determine human ear wax type. The G/G and G/A genotypes correspond to the wet type, while the A/A genotype corresponds to the dry type. Another earwax determinant, a 27-bp deletion (Δ27) downstream from the rs17822931 site, is a rare variant that leads to the dry phenotype. In a previous report, we found an individual with the G allele who unexpectedly showed the dry type of earwax, leading to the identification of Δ27. We also demonstrated that the Δ27 allele was present in individuals of Japanese, Thai, native North American, Andean, and Bolivian ancestry but absent in those of European and African ancestry. Here, we assessed the Δ27 allele frequency among Japanese and Ukrainian individuals and identified a novel association between the Δ27 and 538G>A mutations. The Δ27 allele frequency was 0.002 (3/1,520; one individual is heterozygous, and another is homozygous) among Japanese individuals and 0 (0/794) among Ukrainians. We also found a previously unreported homozygous genotype for both the Δ27 and A alleles. Our findings suggest that the Δ27 deletion may have occurred in an ABCC11 gene with the 538G>A mutation.

Abstract
Differential cross sections and photon-beam asymmetries for the γ[over →]p→π^{-}Δ^{++}(1232) reaction have been measured for 0.7<cosθ_{π}^{c.m.}<1 and E_{γ}=1.5-2.95 GeV at SPring-8/LEPS. The first-ever high statistics cross-section data are obtained in this kinematical region, and the asymmetry data for 1.5<E_{γ}(GeV)<2.8 are obtained for the first time. This reaction has a unique feature for studying the production mechanisms of a pure uu[over ¯] quark pair in the final state from the proton. Although there is no distinct peak structure in the cross sections, a non-negligible excess over the theoretical predictions is observed at E_{γ}=1.5-1.8 GeV. The asymmetries are found to be negative in most of the present kinematical regions, suggesting the dominance of π exchange in the t channel. The negative asymmetries at forward meson production angles are different from the asymmetries previously measured for the photoproduction reactions producing a dd[over ¯] or an ss[over ¯] quark pair in the final state. Advanced theoretical models introducing nucleon resonances and additional unnatural-parity exchanges are needed to reproduce the present data.

Abstract
Spontaneously Diabetic Torii (SDT) fatty rats, a new obese diabetic model, reportedly presented with features of non-alcoholic steatohepatitis (NASH) after 32 weeks of age. We tried to accelerate the onset of NASH in SDT fatty rats using dietary cholesterol loading and noticed changes in the blood choline level which is expected to be a NASH biomarker. Body weight and biochemical parameters were measured from 8 to 24 weeks of age. At 16, 20, 24 weeks, pathophysiological analysis of the livers were performed. Hepatic lipids, lipid peroxides, and the expression of mRNA related to triglyceride (TG) synthesis, inflammation, and fibrosis were evaluated at 24 weeks. Hepatic fibrosis was observed in SDT fatty rats fed cholesterol-enriched diets (SDT fatty-Cho) from 16 weeks. Furthermore, hepatic lipids and lipid peroxide were significantly higher in SDT fatty-Cho than SDT fatty rats fed normal diets at 24 weeks. Hepatic mRNA expression related to TG secretion decreased in SDT fatty-Cho, and the mRNA expression related to inflammation and fibrosis increased in SDT fatty-Cho at 24 weeks. Furthermore, SDT fatty-Cho presented with increased plasma choline, similar to human NASH. There were no significant changes in the effects of feeding a cholesterol-enriched diet in Sprague-Dawley rats. SDT fatty-Cho has the potential to become a valuable animal model for NASH associated with type 2 diabetes and obesity.

Abstract
The efficacy, safety, and pharmacokinetics of bisoprolol were investigated following oral administration once daily for 12 weeks in hyperreninemic patients with dialysis-refractory hypertension. Mean blood pressure rapidly fell from 132 to 112 mmHg in the 5.0-mg/day (n = 6) and from 142 to 128 mmHg in the 2.5-mg/day patients (n = 5), which were accompanied by a fall in plasma renin activity. On nondialysis days, Cmax and T1/2 were significantly higher in patients than in healthy control subjects. However, Cmax in the 2.5-mg/day patients was almost equal to that in healthy control subjects receiving 5.0 mg/day of bisoprolol. Plasma bisoprolol was dialyzable. During the course of the study, dialysis hypotension and bradycardia occurred in two patients receiving 5.0 mg/day of bisoprolol. In conclusion, a daily dose of 2.5 mg bisoprolol seems to be an adequate and relatively effective dose in our patients with dialysis-refractory hypertension.
